packing Explanation: it is the packing around a joint in order to reduce vibration/movement and hence leakage. -------------------------------------------------- Note added at 33 mins (2004-07-04 12:16:41 GMT) -------------------------------------------------- see for instance: http://www.tpub.com/content/fc/14104/css/14104_167.htm \"Valves are components used to control the transfer of liquids and gases through fluid piping systems. Most valves have moving joints between the valve stem and the bonnet. When fluid is on one or both sides of a moving joint, the joint may leak. Sealing the joint prevents this leakage. Sealing a moving joint presents a problem because the seal must be tight enough to prevent leakage, yet loose enough to let the valve stem turn without binding. Packing is the most common method of sealing a moving joint\" |
